TETRACHLOROETHYLENE (PCE)

TRICHLOROETHYLENE (TCE)..

PCE was detected  in  all  but  one  soil  sample  at  concentrations ranging  from  0.17J µg/kg  to  4,900  µg/kg.    The  highest  PCE  was  reported  in  the  sample  collected  at 25  feet  bgs  from  boring  SB-7.    Boring  SB-7  is  located  near  the  degreaser  area just  to  the  north  of  Building  10.   TCE  was  detected  in  91  of  the  130  soil  samples  collected  at  concentrations ranging  from  0.28J  µg/kg  to  380  µg/kg.    The  highest  TCE  was  detected  in  a sample  collected  at  30  feet  bgs  from  boring  SB-12.  Boring  SB-12  is  located southeast  of  Building  10.   cis-1,2-DCE  was  found  in  51  of  the  130  soil  samples  collected  at  concentrations ranging  from  0.22J  µg/kg  to  170  µg/kg.    The  highest  cis-1,2-DCE  was  detected  in a  sample  collected  at  10  feet  bgs  from  boring  SB-12.  Boring  SB-12  is  located southeast  of  Building  10.   Trans-1,2-DCE  was  found  in  19  of  the  130  soil  samples  collected  at concentrations  ranging  from  1.2  µg/kg  to  42  µg/kg.    The  highest  trans-1,2-DCE was  detected  in  a  sample  collected  at  10  feet  bgs  from  boring  SB-12.  Boring  SB12  is located  southeast  of  Building  10.   1,1-DCE  was  found  in  11  of  the  130  soil  samples  collected  at  concentrations ranging  from  0.34J  µg/kg  to  2.1  µg/kg.    The  highest  trans-1,2-DCE  was  detected in  a  sample  collected  at  30  feet  bgs  from  boring  SB-11.  Boring  SB-11  is  located between  Buildings 9  and  10.   Vinyl  chloride  was  detected  in  8  of  the  130  soil  samples  collected  at concentrations  ranging  from  0.63J  µg/kg  to  7  µg/kg.    The  highest  vinyl  chloride was  detected  in  a  sample  collected  at  10  feet  bgs  from  boring  SB-12.  Boring  SB12  is located  southeast  of  Building  10.
